The Pretty Little Liars hottie posted this adorable baby photo yesterday (May 13), showing off him and his mother (we mean, mum) laying out on the beach. And yes, Julian is in his baby birthday suit. He wrote, "#toohot4instagram." How adorable!

And Julian's not the only one who took us back in time around Mother's Day. Lucy Hale (Aria) also showed off a cute pic of her and her mom from her childhood. Who's your favorite PLL baby? Let us know in the comments below!
